| Terms for subject Environment (7358 entries) |
| racking (The mechanical dewatering of a wet solid by pouring off the liquid without disturbing the underlying sediment or precipitate) | 分离 | |
| radar (A system using beamed and reflected radiofrequency energy for detecting and locating objects, measuring distance or altitude, navigating, homing, bombing and other purposes) | 雷达 | |
| radiation (Emission of any rays from either natural or man-made origins, such as radio waves, the sun's rays, medical X-rays and the fall-out and nuclear wastes produced by nuclear weapons and nuclear energy production. Radiation is usually divided between non-ionizing radiation, such as thermal radiation (heat) and light, and nuclear radiation. Non-ionizing radiation includes ultraviolet radiation from the sun which, although it can damage cells and tissues, does not involve the ionization events of nuclear radiation) | 辐射 | |
| radiation adaptation | 辐射适应 | |
| radiation and contamination control | 放射与污染控制 | |
| radiation damage (Somatic and genetic damage to living organisms caused by exposure to ionizing radiation) | 辐射破坏 | |
| radiation dose (The total amount of radiation absorbed by material or tissues, in the sense of absorbed dose, exposure dose, or dose equivalent) | 辐射剂量 | |
| radiation effect (Prolonged exposure to ionizing radiation from various sources can be harmful. Nuclear radiation from fallout from nuclear weapons or from power stations, background radiation from substances naturally present in the soil, exposure to X-rays can cause radiation sickness. Massive exposure to radiation can kill quickly and any person exposed to radiation is more likely to develop certain types of cancer than other members of the population) | 辐射效果 | |
| radiation effects | 辐射作用 | |
| radiation exposure (The act or state of being subjected to electromagnetic energy strong enough to ionize atoms thereby posing a threat to human health or the environment) | 辐射暴露 | |
| radiation fog | 辐射雾 | |
| radiation frost | 辐射霜［冻］ | |
| radiation heat | 辐射热 | |
| radiation monitoring (The periodic or continuous surveillance or analysis of the level of radiant energy present in a given area, to determine that its prescribed amount has not been exceeded or that it meets acceptable safety standards) | 辐射监控 | |
| radiation physics (The study of ionizing radiation and its effects on matter) | 辐射物理学 | |
| radiation protection (Precautionary actions, measures or equipment implemented to guard or defend people, property and natural resources from the harmful effects of ionizing energy) | 辐射防护 | |
| radiation protection law (A binding rule or body of rules prescribed by government to establish measures to keep humans and natural resources safe from harmful exposure to energy waves released by nuclear materials, electromagnetic current and other sources) | 辐射防护法 | |
| radiation sickness (The complex of symptoms characterizing the disease known as radiation injury, resulting from excessive exposure of the whole body (or large part) to ionizing radiation. The earliest of these symptoms are nausea, fatigue, vomiting, and diarrhea, which may be followed by loss of hair (epilation), hemorrhage, inflammation of the mouth and throat, and general loss of energy) | 辐射病 | |
| radiation stress | 辐射胁迫 | |
| radio (The process, equipment or programming involved in transmitting and receiving sound signals by electromagnetic waves) | 无线电 |
